Hi I have taken off the pollen filter on right hand drive fabia

Firstly how does the pollen filter fit in the casing and secondly does the air flow arrow point to drivers side or passenger side of vehicle ?

Thanks

Points to the drivers side indicating the air flow, they just push vertically upwards.

There are two tabs which you slide to retain the filter once it's installed. You must have done all this to remove the old one, re-assembly, as they say, is the reverse order of disassembly.
